      ************************************************************************************************
      I USE OEL5.8 FOR 11GR2 FOR EASY INSTALLATION BUT IT IS DISAPPOINTING.
      ON GOOGLE A LOT OF GUIDE, A LOT OF ERROR ,A LOT OF IGNORE SUGGESTION FOR SETUP.

      I ASK ORACLE IS THERE ANY ONE MAKE THIS INSTALLATION EASY.
      ************************************************************************************************


      Linux rac1.testonline.com 2.6.32-300.10.1.el5uek #1 SMP Wed Feb 22 17:37:40 EST 2012 x86_64 x86_64 x86_64 GNU/Linux

      oracle 11gr2.patch set 3 (p10404530_112030_Linux-x86-64.......)

      HP P2000 FC
      2xHP DL380 2XFC (multipath)

      Multipath ASM. (This is also a need lot of research )

      /etc/multipath.conf
      multipath {
      wwid 3600c0ff000118e292e0d575001000000
      alias asmora
      uid oracle *************this is must be write in this file.................
      gid oinstall
      }



      Both server same configuration DNS with reverse lookup work well from both server with oracle,root users
      All setting correct asm , ethernet , ssh ...

      ./runcluvfy.sh stage -pre crsinst -n rac1.testonline.com,rac2.testonline.com -verbose

      rac2 failed
      rac1 passed
      PRVF-5636 : The DNS response time for an unreachable node exceeded "15000" ms on following nodes: rac2

      Give a error like that.
